While Exch still continues to function properly, during Mozilla’s review process for the latest update, it was stalled (for good reason). For any future versions to be approved, code changes will be required.
This version didn’t pass full review because of the following issues:
- The codebase_principal_support preference and enablePrivilege function are considered unsafe to use and support for them will be removed from Firefox very soon: https://bugzilla.mozilla.org/show_bug.cgi?id=546866.
Exch was and still is a pretty cool extension, but its task is better served via sites like Yahoo! Finance, or Google Finance. Plus, with all of the cool things you can do with Google Search (as I have posted about before), or Yahoo having a slick currency conversion tool on their site, I feel I have run out of reasons to maintain it.
With all of that said, the last update will be exch-1.5.0-fx. While it -should- work with Firefox 4 and 5, let’s call it “beta”. A beta perpetually stuck at version 1.5.0. 😉
